You can remove poison counters in Magic: The Gathering, but only a small number of cards can do it directly. The classic answer is Leeches, a white sorcery that makes a target player lose all poison counters and then deals that much damage to that player. Most of the cards described as “poison counter answers” don’t remove anything at all: they prevent new counters, stop the damage that would give you counters, or help you win before poison becomes lethal.
That distinction matters because poison counters are not life points. Gaining twenty life does not remove a single poison counter, and clearing -1/-1 counters off a creature doesn’t undo the poison already on a player.
How poison counters cause you to lose
In ordinary Magic games, a player with ten or more poison counters loses the game as a state-based action. It doesn’t wait for the end of the turn, and it doesn’t use the stack. When the game checks state-based actions and sees ten poison counters, the player loses before anyone can cast a last-second spell in response.
Poison counters can arrive through several mechanics and card effects:
- Infect: damage dealt to a player by a source with infect causes that player to receive that many poison counters instead of losing that much life.
- Toxic: when a creature with toxic deals combat damage to a player, that player receives the number of poison counters specified by the toxic ability, in addition to the normal damage and life loss.
- Proliferate: an effect can add an additional poison counter to a player who already has one or more, if that player is chosen during the proliferate effect.
- Other card text: certain spells and abilities directly give players poison counters without using infect or toxic.
The complete rules are maintained by Wizards of the Coast. Its Phyrexia: All Will Be One release notes offer especially readable examples of toxic and proliferate.
Cards that really remove poison counters
| Card | What it actually does | Main limitation |
|---|---|---|
| Leeches | Target player loses all poison counters; Leeches deals that much damage to that player | You still take damage, which can be lethal at low life |
| Suncleanser | Its opponent-targeting mode makes a target opponent lose all counters and prevents more while Suncleanser remains | You cannot choose yourself as the target of that mode |
| Solemnity | Prevents players from getting counters while it applies | Does not remove counters already present |
| Melira, Sylvok Outcast | Stops you from receiving poison counters while it applies | Does not remove existing poison counters |
The first two entries are genuine removal effects under the right targeting conditions; the last two are prevention. Those are very different jobs.
Leeches: the straightforward answer, with a painful catch
Leeches costs {1}{W}{W}. Its current rules text removes all poison counters from a target player and deals that much damage to that player. You can target yourself.
Suppose you’re at seven poison counters and sixteen life. Resolve Leeches targeting yourself: you lose all seven poison counters, then take seven damage. You end up at zero poison counters and nine life, assuming nothing modifies the damage.
But if you are at seven poison counters and five life, removing the counters doesn’t guarantee survival. The damage from Leeches can take you to zero life. Life gain or damage-prevention effects may help, but those require their own timing and rules checks.
Leeches is an unusually direct poison solution, not an automatically strong inclusion in every white deck. It is situational against a strategy some pods rarely face. In a poison-heavy local metagame it becomes more interesting; elsewhere, a flexible interaction spell is often better deckbuilding value.
Suncleanser: a trap if you want to cure yourself
Suncleanser can make a target opponent lose all counters. Because the effect explicitly says opponent, you cannot point it at yourself to remove your own poison. You could remove an opponent’s poison counters, which may be useful in unusual multiplayer situations, but most players looking for an antidote have the targeting backward.
Suncleanser also has a creature-counter mode that targets a creature and removes its counters. That mode is about the creature, not the poison counters on its controller. The distinction is easy to miss when a card says “remove all counters” in large, promising letters.
Cards that stop new poison counters
Prevention is often better than emergency removal, especially if you can deploy it before the first infect attack.
Solemnity says players can’t get counters. While it’s on the battlefield, the relevant prevention protects players from new poison counters. Existing poison counters remain; if Solemnity leaves, they still count toward the lethal threshold.
Melira, Sylvok Outcast prevents you from receiving poison counters while the creature remains. It also interacts with -1/-1 counters on your creatures. Again, it does not undo poison already acquired. A protection effect that lasts one turn or until a permanent leaves should never be mistaken for a permanent poison reset.
There are more specialized effects, but ask whether the card is actually likely to resolve before poison becomes a threat. A narrow answer that sits dead in hand for ten games is not automatically better than broad removal or interaction.
Can you prevent poison by preventing damage?
Often, yes. Infect and toxic depend on damage in different ways, but both create opportunities to defend yourself before counters are applied.
An infect creature dealing damage to a player normally converts that damage into poison counters. Preventing the damage prevents that route to poison. Toxic gives poison counters when the creature deals combat damage to a player, so preventing all of that combat damage also keeps toxic from triggering on that damage event.
You can also stop the attack through normal Magic interaction: remove or tap the attacking creature before combat damage, create an effective blocker, or use a protective instant as appropriate. These are good answers because they often remain useful against non-poison decks.
What doesn’t work is gaining life after you’ve already accumulated poison counters. A player at 40 life and nine poison counters is still one poison counter away from losing.
Does proliferate remove or add poison counters?
Proliferate normally adds counters; it does not remove them. When an effect tells you to proliferate, you choose any number of permanents or players that already have counters, and give each an additional counter of each kind they already have. Choosing an opponent who has poison counters can increase their total. Choosing yourself would increase yours, so don’t do that just because you can.
This makes the first poison counter strategically important. A creature that gives only one poison counter may not look dangerous, but once that counter exists, proliferate effects can apply pressure without another creature connecting in combat.
We have a separate guide to how many poison counters it takes to win. This article focuses on removing or preventing them, not on the basic win condition.
Commander-specific decisions
In Commander, players still normally lose to ten poison counters; starting at 40 life does not raise that threshold to 20 or 40. That gives poison decks a distinctive angle of attack, but it also means an entire table may start interacting with the poison player once the threat is visible.
Before dedicating several slots to anti-poison cards, ask how often the problem comes up in your actual games. If one opponent reliably plays infect, a targeted prevention effect may be worth testing. In a general-purpose pod, cards that answer creatures and protect your board are often the more flexible starting point.
If you’re testing a poison deck yourself, proxy a small package of infect and proliferate cards and watch how much of the pressure comes from the first combat-damage connection. That’s usually more informative than merely counting how many cards in the deck say “poison.”
Frequently asked questions
Can you remove poison counters by gaining life?
No. Life totals and poison counters are separate. Gaining life doesn’t change your poison-counter total unless a specific card explicitly says it does, and ordinary life-gain cards don’t.
Does poison reset at the end of a turn?
No. Poison counters remain on a player across turns until an effect removes them or the game ends.
Can Leeches save you when you already have ten poison counters?
Normally no. You lose as a state-based action before you can cast a sorcery after reaching ten counters. Leeches needs to resolve before the lethal condition is reached, barring a separate effect that prevents you from losing.
Does Suncleanser remove poison counters from its controller?
No. Its player-counter-removal mode targets an opponent, not its controller. It can remove an opponent’s poison counters, which is usually not what the player trying to survive infect wants.
Does protection from a color stop poison?
Protection can prevent damage from an appropriately colored source, which can stop damage-based infect or toxic. It does not universally prevent a separate effect from giving you counters when that effect doesn’t rely on damage, targeting, or one of protection’s other relevant restrictions.
The takeaway
If you need to remove poison counters already on yourself, Leeches is the clearest direct card to know. If you want a generally useful plan, prevent the damage, remove the source, and consider targeted prevention only when your metagame justifies it. Poison is a race you usually want to interrupt before the counters arrive—not a life total you can heal afterward.
